Fleeing starvation during the Great Famine, Irish immigrants poured into New York in the mid-19th century in search of a better life. Working on the docks, many settled in Hell’s Kitchen, then a squalid, crime-ridden. and overcrowded slum, where they struggled to survive poverty and overcome discrimination. Today, the abattoirs, prostitution, gang fights, and sweaty old Madison Square Garden are gone, but in a walking tour timed to celebrate St. Patrick’s Day, New School and NYU Manhattan history instructor Joyce Gold leads a walking tour to explore how that past influences the neighborhood today. Meet at the southeast corner of 43rd St. & Ninth Ave. on Mar. 15, 10:30 a.m. for a 90-min. tour. Tickets are $35 at 92y.org.
